GEORGE IV. KELLEY, OF GOSHEN, INDIANA, ASSIGNOR TO LENVIS H. NOBLE AND JOSEPH M. NOBLE, BOTH OF SAME PLACE.

CARPET-SWEEPER.

SPECIFICATION forming part of Letters Patent No. 330,590, dated November 1'7, 1885. Application filed May 31, 1884. Serial No. 133,299. Modeh) To all whom it may concern.-

Be it known that I, GEORGE WV. KELLEY, of Goshen, county of Elkhart, Indiana, have invented a new and useful Improvement in Carpet-Sweepers, of which the following is a full, clear, and exact description.

The object of my invention is to provide certain new and useful improvements in carpet-sweepers, whereby the same will be rendered more effective and durable.

The invention consists in parts and details and combinations of the same, as will be fully set forth and claimed hereinafter.

Reference is to behad to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a longitudinal elevation of my improved carpet-sweeper, parts being broken out and others shown in section. Fig. 2 is a cross-sectional elevation of the same on the line a: 00, Fig. 1, and Fig. 3is a cross-sectional elevation of the same on the line 1 y, Fig. 1. Fig. 4 is a detail View showing the screw and part of the wire bail.

The box A has a hinged part, B, at one end of its top, and this hinged part is provided with a catch or latch, (J, for keeping the hinged part closed. The revolving brush D, which can be of any suitable construction, is provided with a friction disk or roller, E, on one end, which disk E rests on two frictionrollers, F, having rubber rims F, and jour naled in plates G, provided at their ends with extended notches 9, into which studs H pass, projecting from the inner surface of the end piece of the box A. Studs J project from the adjoining ends of the plates G, and around the said studs a rubber band, K, is passed, which pulls the adjoining ends of the plates G toward each other, and presses the rollers F against the friction-disk E on the brush. The brush-spindle is provided on each end with a projecting pivot, L, of which one is passed in between the prongs of a fork, M, the said fork being fastened to the inner surface of one end of the box. One prong of the fork is longer than the other, and adjoining the short prong a spring, N, is secured on the fork, the bent lower end of the said spring extending under the opening of the fork and preventing the pivot L from dropping out from between the prongs of the fork. A screw, 0, is screwed through the top cross-piece of the fork M, and rests on the pivot L. The top of the screw is provided with a head, 0, projecting from the top of the box. The other pivot L of the brush passes into an'upright groove, 1?, in the inner surface of the corresponding end piece, the groove being provided at its lower end with a staple, P, for holding a pivot in the groove. The bottom Q, of the box is provided with a slot, Q, on the edges of which upwardly and inwardly bent flanges It are formed.

box, and at its middle it is bent to form a prong, V, into which a screw, U, is passed, which is provided with longitudinal grooves for receiving the sides of the prong. The screw U is then screwed into the handle IV. By means of the screw 0 the brush can be adjusted to project a greater or less distance from the bottom of the box. If the brush is to be reremoved, it need only be pulled out, and if it l is to be replaced one pivot L is passed into the groove P, and the other pressed in between the prongs of the fork M. A shoe, Q is preferably secured to the bottom edge of each end piece of the box.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. In a carpet-sweeper, the combination, with the box A and the revolving brush D, of the fork M, fastened on the inner end of said box and having a long and short prong, the spring N, secured to the short prong and having a curved end extending inward across the open end of the fork, and the screw 0, passed through the top of the box and down to the brush-pivot held in the fork, substantially as set forth.

2. In a carpet-sweeper, the combination, with the box and the brush-roller journaled therein, and provided at one end with a frietion-roller, of plates G, slotted at their opposite ends, pins H at opposite sides of the friction-roller and extending into the slotted ends ofthe plates, a friction-roller journaled in each of said plates, and a spring for forcing said IOO plates G toward each other, substantially as set forth.

The U-shaped bail s has its 65 'ends passed into sockets T on the ends of the 3. In a carpet-sweeper, the combination, with the box having a groove, 1?, in one end piece and a fork, M, on the other end piece, of the staple P in the bottom of the groove P, the spring N on the fork, and the brush D, provided with pivot L at each end, substantially as herein shown and described.

4. In a carpet-sweeper, the combination, with the box and the brushing mechanism therein, of the bail bent at its middle to form a prong, V, the screw U Within the prong, and

provided with longitudinal grooves for receiving the two arms of the prong, and handle W, substantially as set forth.

5. The combination, with the bent prong V I 5 of a handle, of a screw having longitudinal grooves for receiving thetwo arms of the prong, substantially as set forth.

GEORGE W. KELLEY.
